Bates has said that the way the investigation is being handled is unfair on QPR and their Championship competitors.
"This is chaos and an utter shambles," Bates told The Sun. "It's not fair on the other clubs and it's not fair on QPR.
"What I can't understand is that they've known about this since September and it's taken eight months to put a hearing together.
"Now it's going on in the last week of the normal season and they can't finish it in time.
"And how can they say the dates for the play-offs are happening without knowing the outcome of this hearing?"
